Abstract
Self-propagating high-temperature synthesis (SHS) has been successfully dev eloped for the fabrication of cellular NiTi intermetallic compounds, which have an open cellular structure with about 60 vol% porosity and more than 9 5% open-porosity ratio. The SHS reactions lead to the formation of TiNi, Ti 2Ni, Ni3Ti, and Ni4Ti3 intermetallics. The SHS process can be controlled by regulating the preheating temperature, which has effects on the phase amou nt and the shape as well as macrodistribution of pores in the products.
